Revisiting TOI-4438 and TOI-442 planetary systems with new observations from SPIRou and TESS
J. Serrano Bell, G. Hébrard, E. Martioli +26
We present a comprehensive re-analysis of two star-planet systems: TOI-4438, an M3.5V star hosting a mini-Neptune in a 7.4-day orbit, and TOI-442, an M1V star with a 4-day period p…
The SPIRou Legacy Survey: Detection of a nearby world orbiting in the habitable zone of Gl725B achieved by correcting strong telluric contamination in near-infrared radial velocities with WAPITI
M. Ould-Elhkim, C. Moutou, J. -F. Donati +15
M dwarfs are prime targets in the search for exoplanets because of their prevalence and because low-mass planets can be better detected with radial velocity (RV) methods. In partic…
Characterizing planetary systems with SPIRou: questions about the magnetic cycle of 55 Cnc A and two new planets around B
C. Moutou, P. Petit, P. Charpentier +12
One of the first exoplanet hosts discovered thirty years ago, the star 55 Cnc has been constantly observed ever since. It is now known to host at least five planets with orbital pe…
Characterizing planetary systems with SPIRou: Detection of a sub-Neptune in a 6-day period orbit around the M dwarf Gl 410
A. Carmona, X. Delfosse, M. Ould-Elhkim +42
The search for exoplanets around nearby M dwarfs represents a crucial milestone in the census of planetary systems in the vicinity of our Solar System. Since 2018 our team is carry…
TOI-3568 b: a super-Neptune in the sub-Jovian desert
E. Martioli, R. P. Petrucci, E. Jofre +42
The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…
TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS
Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57
We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…
